Combinatorial analyses of the shikimate module for improving l-tyrosine production in strain B
| Plasmid coexpresseda | % Improvementb |
|---|---|
| pBbB5c::ydiB | 4.4 ± 0.2 |
| pBbB5c::aroE | 9.9 ± 0.6 |
| pBbB5c::aroD | 10.9 ± 0.7 |
| pBbB5c::aroBop | 3.4 ± 0.2 |
| pBbB5c::aroG | 33.5 ± 1.6 |
| pBbB5c::tktA | 20.2 ± 1.1 |
| pBbB5c::ppsA | 14.5 ± 1.0 |
a
The description of plasmid pBbB5c can be found in Table 1. The genes ydiB through tktA were individually cloned into pBbB5c and transformed into strain B.
b
The percent improvement in l-tyrosine production was calculated based on the l-tyrosine titer of strain B.
